Abstract (en)
[origin: EP3316400A1] Embodiments of the present invention provide a phased array system and a beam scanning method. The phased array system includes at least two traveling wave antennas (21) arranged in parallel, and each traveling wave antenna (21) includes at least two antenna units (22) sequentially connected; and a first end (23) of each traveling wave antenna (21) connects to a corresponding first radio frequency channel (20), the first end (23) of each traveling wave antenna (21) connects to a signal processing module (24) of the phased array system by using the corresponding first radio frequency channel (20), and a phase and/or an amplitude of a signal inputted by the signal processing module (24) from the first end (23) into the traveling wave antenna (21) may be adjusted by adjusting a configuration of the first radio frequency channel (20). According to the phased array system and the beam scanning method, based on implementation of spatial beam scanning, a requirement for a quantity of radio frequency channels is reduced, and therefore complexity and costs of the phased array system are reduced.
